Abstract
A combustor which can be manufactured without requiring large-scale equipment and with a small number of processes and has a cooling fluid flow path sealed with high reliability. The combustor includes an inner cylinder made of metal constituting a combustion chamber, a cooling fluid flow path formed on an outer surface of the inner cylinder, and a sealing layer covering the outer surface of the inner cylinder to seal the cooling fluid flow path. The sealing layer is constituted by a bonded body of metal wires wound around the outer surface of the inner cylinder and metallurgically bonded to each other, and the sealing layer is bonded to the outer surface of the inner cylinder by metallurgical bonding.
Claims8
A combustor for a rocket engine comprising:
- an inner cylinder made of metal constituting a combustion chamber;
- a cooling fluid flow path formed on an outer surface of the inner cylinder;
- and
- a sealing layer covering the outer surface of the inner cylinder to seal the cooling fluid flow path,
- wherein the sealing layer is:
- constituted by a bonded body of metal wires wound around the outer surface of the inner cylinder, the bonded body being bonded by metallurgically bonding;
- and
- bonded to the outer surface of the inner cylinder by the metallurgical bonding.
A method for manufacturing a combustor for a rocket engine comprising:
- forming a cooling fluid flow path on an outer surface of an inner cylinder made of metal that constitute a combustion chamber;
- winding metal wires around the outer surface of the inner cylinder;
- and
- sealing the cooling fluid flow path by heating the inner cylinder, around which the metal wires are wound, to a temperature equal to or higher than a diffusion temperature of the metal wires to diffusion-bond the metal wires to each other and diffusion-bond the metal wires and the inner cylinder.
A method for manufacturing a combustor for a rocket engine comprising:
- forming a cooling fluid flow path on an outer surface of an inner cylinder made of metal that constitute a combustion chamber;
- sticking solder material to at least one of the outer surface of the inner cylinder and metal wires;
- winding the metal wires around the outer surface of the inner cylinder;
- and
- sealing the cooling fluid flow path by heating the inner cylinder, around which the metal wires are wound, to a temperature equal to or higher than a melting temperature of the solder material to braze the metal wires to each other and braze the metal wires and the inner cylinder.
